Who is choosing the drinks?

Adults who prefer a smaller can

For a takeaway evening, a 250ml can may be easier to fit into your plans than a 500ml can. Red Bull states that its Original and Zero 250ml cans each contain 80mg caffeine; Monster Energy lists 160mg in each named 500ml Original Green and Absolutely Zero can. Count other caffeine you have had as well as the can you choose.

Shoppers choosing between sugar and sweeteners

Red Bull Zero and Monster Absolutely Zero offer zero-sugar routes at different can sizes. Check the exact variant: Monster Energy lists 0g sugar for Absolutely Zero but 55g per 500ml can for Original Green. A zero-sugar label does not mean caffeine-free.

Hosts serving a mixed-age group

Keep a non-caffeinated sparkling choice available rather than treating energy drinks as drinks for every guest. For England, the Department of Health and Social Care announced an under-16 sales restriction on high-caffeine energy drinks from April 2027, subject to Parliamentary approval; check the position when you buy.

What should you check?

Start with caffeine in the whole can, then compare sugar content and the drink style you actually want alongside the takeaway.

Priority What to check Your needs
Caffeine per can Compare the full-can amount and can size. Red Bull lists 80mg in each named 250ml Original or Zero can; Monster Energy lists 160mg in each named 500ml Original Green or Absolutely Zero can. Count caffeine from other drinks too. I would rather choose a smaller stated caffeine amount for one can, especially if I have already had tea, coffee or another caffeinated drink.
Sugar or sweeteners Check the exact regular or zero-sugar variant and compare sugar on the same per-can basis. Monster Energy lists 55g sugar in a 500ml Original Green can and 0g in a 500ml Absolutely Zero can. Do I want a zero-sugar drink that uses sweeteners, or do I prefer a regular sugared formula? The name of the brand alone will not tell me which one I am picking up.
Fizz and flavour Confirm that the particular drink is carbonated. Lucozade describes its Energy range as sparkling and containing glucose; Tesco describes Relentless Origin 500ml as carbonated. Check the exact pack for its flavour and nutrition information. I want a fizzy drink with the takeaway, but I would choose its flavour for my own taste rather than assume one energy drink pairs with every Chinese dish.
Who will drink it Provide a non-caffeinated option for younger guests. The Department of Health and Social Care announced an England under-16 sales restriction on high-caffeine energy drinks from April 2027, subject to Parliamentary approval. The NHS advises a maximum of 200mg caffeine a day during pregnancy, counting all sources. If I am buying for several people, I need drinks they can each choose appropriately, not just one multipack for the whole group.

Common buying mistakes

  • Reading “zero sugar” as “no caffeine”

    Monster Energy lists 160mg caffeine in a 500ml Absolutely Zero can despite its 0g sugar; Red Bull lists 80mg in a 250ml Zero can.

    Check sugar and caffeine separately, using the amount for the whole can you intend to drink.

  • Comparing can sizes without checking caffeine

    The named 500ml Monster Original Green and Absolutely Zero cans each contain 160mg caffeine, according to Monster Energy. Red Bull lists 80mg in each named 250ml Original or Zero can.

    Compare the stated caffeine per can alongside volume, particularly if you have already had caffeinated drinks that day.

  • Assuming two retailer listings describe the same nutrition figures

    Tesco and Sainsbury's both identify Relentless Origin as a 500ml carbonated drink, but their displayed nutrition information differs. That makes a cross-retailer sugar comparison for this product uncertain.

    Use the nutrition panel and caffeine warning on the pack you are buying when those figures matter to your choice.

  • Buying energy drinks as the only option for younger guests

    The Department of Health and Social Care announced an under-16 sales restriction on high-caffeine energy drinks in England from April 2027, subject to Parliamentary approval.

    Offer non-caffeinated drinks at a shared takeaway and check the current position before buying for an under-16.

Brands and retailer references

These references describe particular ranges or listings; they do not mean every product from a brand has the same ingredients or can size.

Red Bull

Red Bull states that its Original and Zero drinks each contain 80mg caffeine per 250ml can.

  • Zero is the zero-sugar variant; the two named cans offer a smaller serving than the 500ml Monster formats discussed here.
  • Both named Red Bull variants contain caffeine, so choosing Zero does not remove the need to count other sources.

Monster

Monster Energy lists 160mg caffeine per 500ml can for Original Green and Absolutely Zero.

  • The brand lists 0g sugar for Absolutely Zero and 55g per can for Original Green, giving a clear distinction between these two named variants.
  • Both are 500ml, 160mg-caffeine cans; do not apply those figures to a different Monster variant without checking it.

Relentless

Tesco identifies Relentless Origin as a carbonated 500ml energy drink; Sainsbury's displays a high-caffeine warning for its Origin listing.

  • Origin is a named carbonated option for shoppers considering a 500ml can.
  • The two retailer nutrition listings differ, so check the current pack before making a sugar or caffeine comparison.

Lucozade

Lucozade describes its Energy range as sparkling and containing glucose.

  • It offers another named sparkling style for a shopper who wants a glucose-containing drink.
  • Check the specific bottle or can for its serving size, sugar and caffeine before comparing it with a named Red Bull or Monster variant.

Tesco

Tesco's energy-drinks category lists brands including Red Bull, Monster and Relentless.

  • Its Relentless Origin listing identifies a 500ml carbonated format.
  • For Relentless Origin nutrition figures, check the physical pack rather than treating different retailers' listings as interchangeable.

Sainsbury's

Sainsbury's lists Relentless Origin as a 500ml energy drink and displays its high-caffeine warning.

  • The listing states a caffeine concentration of 32mg per 100ml for that product.
  • Its nutrition table differs from Tesco's listing for the apparent same product; check the pack in hand.

Questions about the choice

Which named can has the smaller caffeine amount?

Red Bull lists 80mg caffeine in each 250ml Original or Zero can, compared with Monster Energy’s stated 160mg in each 500ml Original Green or Absolutely Zero can. Compare the full-can figure for any other variant rather than applying these amounts across either brand.

Does zero sugar mean an energy drink is caffeine-free?

No. Red Bull Zero contains 80mg caffeine per 250ml can, according to Red Bull, while Monster Energy lists 160mg per 500ml Absolutely Zero can. Check caffeine and sugar as separate label details.

What if younger guests are coming to the takeaway?

Offer a non-caffeinated drink as well as any adult energy-drink options. The Department of Health and Social Care announced an under-16 sales restriction on high-caffeine energy drinks in England from April 2027, subject to Parliamentary approval; check the current position when buying.

What should someone who is pregnant check?

The NHS advises no more than 200mg caffeine a day during pregnancy, with caffeine from energy drinks counting towards that total. Check caffeine from everything consumed that day, not just the can being considered.

Is Lucozade Energy a sparkling alternative?

Yes. Lucozade describes its Energy range as sparkling and containing glucose. Check the exact bottle or can for its caffeine, sugar and serving-size details before comparing it with a particular Red Bull or Monster drink.
